Question

The amount of rhubarb in the original recipe is 3 1/2 cups. Using what you know of whole numbers and what you know of fractions explain how you could triple that mixed number

Answer 1

Well first things first is you got to turn 3 1/2 into a mixed number. All i did was multiply 3x2 and added 1 which gave me 7 so that was my numerator. And for my denominator i kept the 2. So all you got to do now is multiply the fraction by 3 and make sure you put a 1 under 3. It gives you 21/2 so just divide that since its improper.  And then your answer would be 10 1/2. Hope this helped you!

Answer 2

Answer:

$10\frac{1}{2}$ cups.

Step-by-step explanation:

The amount of rhubarb in the original recipe is = $3\frac{1}{2}$ cups.

                                                                             = $\frac{7}{2}$ cups

Using this amount we have to triple that mixed number.

So we have to multiply this fraction by 3.

$\frac{7}{2}$ × 3

= $\frac{21}{2}$

= $10\frac{1}{2}$ cups

We will get $10\frac{1}{2}$ cups when we triple the number of $3\frac{1}{2}$
